FEA Impact test

Michael Dyjach Sep 24, 2012 9:11 AM

I'm trying to set up an impact test. I am impacting my assembly with a 15lb 1.5x3.5 100mph piece of wood. My assembly is basically a 36x36 box. Is there any way to do this? I keep finding myself running into walls.

what are you trying to estimate?

Hi Michael: I believe you can locate the block of wood on the virtual wall. Then, you can launch your assembly into the wood (at whatever angle is appropriate). If gravitational field is important for this study, I believe you can point the field vector in any direction you desire. - Tony

  Using a drop test? or is it a different study?

    As descibed initialy you need to do a NL dynamic study, drop test won't really cut it but if you don't have the NL capabilites then it might offer an approximation.
